I have a 2008 mustang Gt, I've asked a lot of people if I they know what size of tubing I have and none of them know.
Can someone help me? I want to know what size I have and whats the biggest I can go with just bolt ons done to my engine?

2.25" is the stock size, IIRC.

On an aftermarket exhaust, with only bolt-ons, I'd just go with a 2.5".

you actually have 2.5 inch mandral bent exhaust from the factory. if you are going to replace it i would only do a mid pipe just to change the cats and an axle back

Well, it's sorta mandrel bent...I put longtubes on my car and I'm in the process of putting some small Magnapacks in as resonators. The intermediate pipes have all those stupid little bends in them and the pipe diameter is definitely less than 2.5" near the bends.
